The pulp- and paper production is a very energy intensive industry sector. Both Sweden and the U.S. are major pulpandpaper producers. This report examines the energy and the CO2-emission connected with the pulp- and paperindustry for the two countries from a lifecycle perspective.New technologies make it possible to increase the electricity production in the integrated pulp- andpaper mill through black liquor gasification and a combined cycle (BLGCC). That way, the mill canproduce excess electricity, which can be sold and replace electricity produced in power plants. In thisprocess the by-products that are formed at the pulp-making process is used as fuel to produce electricity.In pulp- and paper mills today the technology for generating energy from the by-product in aTomlinson boiler is not as efficient as it could be compared to the BLGCC technology. Scenarios havebeen designed to investigate the results from using the BLGCC technique using a life cycle analysis.Two scenarios are being represented by a 1994 mill in the U.S. and a 1994 mill in Sweden.The scenariosare based on the average energy intensity of pulp- and paper mills as operating in 1994 in the U.S.and Sweden respectively. The two other scenarios are constituted by a »reference mill« in the U.S. andSweden using state-of-the-art technology. We investigate the impact of varying recycling rates and totalenergy use and CO2-emissions from the production of printing and writing paper. To economize withthe wood and that way save trees, we can use the trees that are replaced by recycling in a biomassgasification combined cycle (BIGCC) to produce electricity in a power station. This produces extra electricitywith a lower CO2 intensity than electricity generated by, for example, coal-fired power plants.The lifecycle analysis in this thesis also includes the use of waste treatment in the paper lifecycle. Both Sweden and theU.S. are countries that recycle paper. Still there is a lot of paper waste, this paper is a part of the countries municipalsolid waste (MSW). A lot of the MSW is landfilled, but parts of it are incinerated to extract electricity. The thesis hasdesigned special scenarios for the use of MSW in the lifecycle analysis.This report is studying and comparing two different countries and two different efficiencies on theBLGCC in four different scenarios. This gives a wide survey and points to essential parameters to specificallyreflect on, when making assumptions in a lifecycle analysis. The report shows that there arethree key parameters that have to be carefully considered when making a lifecycle analysis of wood inan energy and CO2-emission perspective in the pulp- and paper mill in the U.S. and in Sweden. First,there is the energy efficiency in the pulp- and paper mill, then the efficiency of the BLGCC and last theCO2 intensity of the electricity displaced by BIGCC or BLGCC generatedelectricity. It also show that with the current technology that we havetoday, it is possible to produce CO2 free paper with a waste paper amountup to 30%. The thesis discusses the system boundaries and the assumptions.Further and more detailed research, including amongst others thesystem boundaries and forestry, is recommended for more specificanswers.

The aim of this paper is to assess the progress of the banking sector before and shortly after the Real Plan. We began by assessing the drop in the inflation revenues (negative real interest rates paid by the excess of demand deposits over total reserve requirements) as a result of the change in inflation from 40% a month for the pre-Real Plan period to a monthly average of 3.65% (IGP-DI), between July 1994 and May 1995. Then, using the financial statement data of a group of 90 banks, we attempt to estimate the net losses due to the inflation drop analyzing the profitability and other parameters of the banking industry. The calculations are made separately for private, state and federal banks. A later analysis on performance using information given to CVM (Securities Exchange Commission) by the six major private banks in the country is also discussed herein.

This paper is a theoretica1 and empirica1 study of the re1ationship between indexing po1icy and feedback mechanisms in the inflationary adjustment process in Brazil. The focus of our study is on two policy issues: (1) did the Brazilian system of indexing of interest rates, the exchange rate, and wages make inflation so dependent on its own past values that it created a significant feedback process and inertia in the behaviour of inflation in and (2) was the feedback effect of past inf1ation upon itself so strong that dominated the effect of monetary/fiscal variables upon current inflation? This paper develops a simple model designed to capture several "stylized facts" of Brazi1ian indexing po1icy. Separate ru1es of "backward indexing" for interest rates, the exchange rate, and wages, reflecting the evolution of po1icy changes in Brazil, are incorporated in a two-sector model of industrial and agricultural prices. A transfer function derived irom this mode1 shows inflation depending on three factors: (1) past values of inflation, (2) monetary and fiscal variables, and (3) supply- .shock variables. The indexing rules for interest rates, the exchange rate, and wages place restrictions on the coefficients of the transfer function. Variations in the policy-determined parameters of the indexing rules imply changes in the coefficients of the transfer function for inflation. One implication of this model, in contrast to previous results derived in analytically simpler models of indexing, is that a higher degree of indexing does not make current inflation more responsive to current monetary shocks. The empirical section of this paper studies the central hypotheses of this model through estimation of the inflation transfer function with time-varying parameters. The results show a systematic non-random variation of the transfer function coefficients closely synchronized with changes in the observed values of the wage-indexing parameters. Non-parametric tests show the variation of the transfer function coefficients to be statistically significant at the time of the changes in wage indexing rules in Brazil. As the degree of indexing increased, the inflation feadback coefficients increased, while the effect of external price and agricultura shocs progressively increased and monetary effects progressively decreased.

The Real Plan has succeeded in stabilizing the Brazilian inflation. The consumer price inflation has been reduced from 11260 percent per year, in June 1994, to an estimate of 8 percent in 1997. The lower inflation resulted in a remarkable income distribution, and in an increased private consumption. The plan managed to control the inflationary effects of the increased demand with some traditional measures: A more liberalized economy, a moving (and overvalued) exchange rate band, high interest rate differentials, and a tight domestic credit policy. The government has, so far failed to accomplish the fiscal adjustment. The price stabilization has largely depended on the current account deficit. However, macroeconomic indicators do not present reasons for concern about the current account sustainability, in the medium-run. The economy may be trapped in a low-growth vicious cycle, represented by a stop-and-go trend, due to the two-way endogencity between domestic saving and growth. Economic growth depends on policies in increase the public sector saving, to secure the privatization of the State enterprises, and to promote investments. The major problem for the government action is, as always, in the political sphere. Approximately 80 percent of the Central Government net revenue are allocated to the social sectors. Consequently, the fiscal reform will hue to deal with the problem of re-designing the public sector’s intervention in the social area. Most probably, it will be inevitable to cut the social area budget. This is politically unpleasant.

As to many Latin american countries, the impacts of the recent economic globalization on the Brazilian economy have revealed a diversified tendency in spatial development when regional economic indicators are observed. This is due to the specificities or each region, as regard their sector structure, the availability of human resources and the degree of technological innovation undertaken by local enterprises. From a situation of regional inequalities observed in lhe socio-economic levels of development at the beginning of the eighties the dynamics of the Brazilian regional evolution has presented different speeds and intensities in the several spaees. This paper aims to evaluate the dynamics of Brazilian regional development during the 1985-95 period and the impacts over the working population and regional disparities in order to offer some elements to assist social and economic policy. For this purpose Dispersion Quotients and Dispersion lntensity Coefficients were calculated based on two variables, the Regional Gross Domestic Product anel the Working Population. The results of the analysis confirm the existence of considerable regional disparities and it was observed that thc sector and regional redistribution of the GDP indicate that in a general way, no remarkable changes occurred in the regional development in the period. The results show that although the economic policies did stimulate a global convergence process of the per capita product among regions, those policies did not attenuate economic dynamism concentration to the desired extent.

This paper aims to evaluate the dynamics of Brazilian regional development during the 1985-95 period. First, regional inequalities indexes were calculated for the whole country’s economy based on the per capita regional income (Williamson Inequality Index), in order to test the convergence or divergence. After this, the analysis aimed to verify the sector and regional dynamics in a more detailed exam, and for this purpose Dispersion Quotients and Dispersion Intensity Coefficients were calculated based on two variables, the Regional Gross Domestic Product and the Working Population. The results of the analysis confirm the existence of considerable regional disparities and it was verified that the sector and regional redistribution of the GDP indicate that, in a general way, no remarkable changes occurred in the regional productive structures in the period. It is also inferred that the economic policy at that period, in spite of resulting in a global regional convergence process of the per capita product, did not avoid the continuation of the concentration of greater economic dynamism in the most advanced regions, nor did it diminish in any considerable way the difference in the degree of development of the Northeast region.

This paper measures the degree of segmentation in the brazilian labor market. Controlling for observable and unobservable characteristics, workers earn more in the formal sector, which supports the segmentation hypothesis. We break down the degree of segmentation by socio-economic attributes to identify the groups where this phenomenon is more prevalent. We investigate the robustness of our findings to the inclusion of self-employed individuals, and apply a two-stage panel probit model using the self-selection correction strategy to investigate a potential weakness of the fixed-effects estimator

In the backdrop of the strict patent regime flatly adopted by the World Trade Organization (WTO) for all countries, a few countries constantly challenge this system through aggressive patent bargains. Within the pharmaceutical sector, noticeably, some countries now threaten to issue or otherwise actually issue compulsory licenses that may sway large pharmaceutical companies into selling drugs with large discounts or into granting voluntary licenses domestically. That is conspicuously the negotiation strategy adopted by Brazil in its negotiations with big international pharmaceutical companies.This paper explains Brazil’s aggressive bargaining approach based on an analysis of two aspects of its political economy. The first has to do with the international context of patent bargaining in the post-WTO era. Accordingly, the existence of large and fast growing domestic markets position countries such as Brazil as strategic destinations for Foreign Direct Investment (FDI) and trade. Together with an absence of a propensity to innovate in pharmaceutical products, these conditions boost Brazil’s bargaining power for issuing compulsory licenses over pharmaceutical products. The second aspect is related to political economy dynamics inside Brazil. Accordingly, the political framework in Brazil undermines long-term policies and favors short-sighted ones also vis-a-vis R&D investments in the pharmaceutical industry. This remains true regardless of the strictness of the patent regime in place. The lesson of Brazil is relevant arguably for other more powerful developing countries which presently examine Brazil's approach while further challenging the WTO's strict patent policy for the future.

This paper studies the electricity load demand behavior during the 2001 rationing period, which was implemented because of the Brazilian energetic crisis. The hourly data refers to a utility situated in the southeast of the country. We use the model proposed by Soares and Souza (2003), making use of generalized long memory to model the seasonal behavior of the load. The rationing period is shown to have imposed a structural break in the series, decreasing the load at about 20%. Even so, the forecast accuracy is decreased only marginally, and the forecasts rapidly readapt to the new situation. The forecast errors from this model also permit verifying the public response to pieces of information released regarding the crisis.

A presente tese engloba cinco trabalhos sobre dois setores brasileiros de infraestrutura: setor de energia e de transportes. No primeiro trabalho, modela-se o lance dos leilões de linhas de transmissão de energia, buscando compreender porque os lances ganhadores têm se situado em níveis abaixo do que se espera. No segundo paper, estima-se a demanda de energia do Brasil e as elasticidades preço e renda que os consumidores apresentem em relação a essa demanda, usando uma técnica ainda não aplicada na literatura e incluindo o período da Crise do Racionamento – a qual pode ter mudado o padrão de consumo dos agentes. No terceiro trabalho, estuda-se a evolução do mercado de gás natural liquefeito (GNL) ao redor do mundo. O GNL pode ser o link que faltava entre os mercados de gás natural e essa hipótese é testada por meio de análises de séries de tempo e de cópulas. O quarto paper discute a entrada do GNL no sistema energético brasileiro e suas eventuais consequências. Por fim, o quinto paper analisa a experiência de leilões de rodovias no Brasil. O trabalho levanta relevantes insights a respeito do modelo de leilão utilizado e dos detalhes contratuais dessas licitações.

The Private Equity Market in Brazil has flourished in the last two decades, and international Funds have been entering the market since then. The activity of these enterprises and how they deal with institutional voids that are present in the brazilian market and the all spheres of distances they have with Brazil are investigated in this research. What are the main challenges for those players in the local market and how private equity functions in Brazil? The first chapter reviews all the literature that concerns private equity in their home countries, such as the United States and Spain (Europe) and Brazil. It also discourses about the concept of private equity in all its different senses, the routine of investees and how is the relationship between Private Equity Fund and Investee. In addition to that, the due diligence process is also explained as well as the private equity sector in Brazil and its regulation. Moreover, the distance between countries and how it affects business is presented followed by the concepts of institutional voids. For the inquiry proposed interviews were conducted in order to capture the perspective of International Private Equity Funds on the Brazilian market. Advent International, The Carlyle Group and Mercapital replied to the inquiries and provided the tools so a picture of the sector was developed. This sector has a range of challenges and opportunities and requires the International Fund to establish a local branch in order to really succeed in the market. The results of this project pointed out to the challenges the market presents and how International Private Funds are coming about it. There are definitely gaps that need to be fulfilled however the industry is going in the right direction. Revenues may change its nature in the next couple of years, however from the Private Equity Fund perspective Brazil has been a worthwhile investment. Nonetheless, it is important to question the vision also of the investee and institutional investor so one can have the entire picture of the sector.

We study the impact of distortions in the investment goods sector on aggregate total factor productivity (TFP). We develop a two-sector neo-classical growth model in which TFP in the capital goods sector relative to TFP in the consumption sector is inversely related to the price of investment relative to consumption, so that we use relative prices to measure TFP in the investment goods sector. The model is calibrated to Brazil and we nd that distortions in the investment goods sector may explain most of the decline in Brazilian TFP relative to the United States since the mid-1970s.

O objetivo desta pesquisa é compreender de que forma as organizações moldam seu ambiente, analisando por que algumas práticas tornam-se reconhecidas como ‘sustentáveis’ na indústria de carne bovina brasileira. O estudo dialoga com a literatura de institucionalismo organizacional ao apontar a necessidade de considerar a política (i.e. as negociações entre atores) e significados, a fim de entender como a estabilidade e a mudança institucional ocorrem em um contexto situado (i.e. em um tempo e espaço específicos). A pesquisa conclui que os entendimentos sobre o que poderia ser reconhecido como ‘sustentabilidade’ são o resultado de atores moldando o seu ambiente por meio de ações e interações que produzem significados. Seguindo uma abordagem de hegemonia, essas disputas não são apenas entre os atores que procuram vantagens recursivas, mas também procuram defender ou atacar as lógicas sociais que apoiam a posição dominante dos atores. Além disso, os atores exercem sua agência sobre as condições no presente (i.e. contexto situado), com base em um passado herdado e com o objetivo de produzir um futuro que eles imaginam. Para analisar tais processos uma abordagem de hegemonia entre atores e lógicas sociais foi desenvolvida para destacar a ordem de negociação, uma arena em que os atores lutam pela hegemonia. Como resultado de tais negociações, uma questão focal emerge, influenciando o discurso e interesses dos atores, bem como justificando as iniciativas, programas e tecnologias sobre tal questão; construindo, portanto, o consenso. Baseando-se em Realismo Crítico e Análise Crítica do Discurso, a pesquisa desenvolveu um estudo de caso longitudinal suportado por documentos públicos e confidenciais e entrevistas com especialistas, para examinar o caminho da sustentabilidade na indústria de carne bovina brasileira. Identificou-se três contextos diferentes para agência em relação à sustentabilidade. Enquanto no primeiro verifica-se um silêncio sobre práticas de sustentabilidade, o segundo enfatiza a emergência do desmatamento da Amazônia como uma questão focal, devido à agência do Greenpeace e MPF que força a indústria a desenvolver um sistema de monitoramento que rastreie seus fornecedores de gado de modo a evitar compra de suprimentos associadas ao desmatamento da Amazônia, dentre outras atividades ilegais. Finalmente, durante o terceiro contexto, o sistema de monitoramento permite que indústria de carne bovina se aproprie da sustentabilidade, assim o setor da carne passa a construir a sua legitimidade para influenciar sobre os riscos e oportunidades associadas ao contexto da sustentabilidade. Em termos de lógicas sociais, o desmatamento na Amazônia foi denunciado como um problema ambiental, nesta indústria, ancorado em algumas características da lógica do capitalismo, como a gestão de riscos, inovação e aumento da produtividade, cadeia de fornecimento global e governança. Embora este ataque questione a racionalidade da maximização racional lucro, impondo restrições ambientais para o comportamento das empresas, a solução desenvolvida é também ancorada sobre as mesmas características do capitalismo empregadas para atacá-lo. Como consequência, uma mudança gradual é ilustrada por uma transformação na ‘eficiência quantitativa’ do capitalismo, o aumento da produtividade devido à mudança da proporção de recursos consumidos para produção e à preocupação em evitar o desmatamento da Amazônia. No entanto, a ‘eficiência qualitativa’ do capitalismo é preservada uma vez que os grupos dominantes no poder ainda estão controlando os meios de produção e os recursos a eles associados (i.e. dinheiro, poder e legitimidade). Uma vez que estes processos de negociações são mediados pela racionalidade de se evitar risco aos negócios, consequentemente, a maximização do lucro, o núcleo duro da lógica do capitalismo é preservado. Portanto, os grupos dominantes mantêm sua hegemonia.

The pattem of a classical hyperinflation is an acute acceleration of the inflation levei accompanied by rapid substitution away from domestic currency. Brazil, however, has becn experiencing inflation leveis well above 1,000% a year since 1988 without entering the classical hyperinflation path. Two elements play key roles in differcntiating the Brazilian case from other hyperinflationary experiences: indexation and the provision of a reliable domestic currency substitute, Le., the provision of liquidity to interest-bearing assets. This paper claims that the existence of this domestic currency substitute is lhe main source of both lhe inability of the Brazilian central bank to fight inflation and of the unwillingness of Brazilians to face the costs of such a fight. The provision of the domestic currency substitute through the banking sector is modeled, and the main macroeconomic consequences of this monetary regime are derived. Those are: the lack of a nominal anchor for the price system due to the passive monetary policy; the endogeneity of seignorage unlikc traditional models of hyperinflation; and lhe ineffectiveness of very high real interest rates.

This paper studies the increase in the rate of informal workers in the Brazilian economy that occurred between 1985 and 1999. We develop an overlapping generations model with incomplete markets in which agents are ex-post heterogeneous. We calibrate it to match some features of the Brazilian economy for 1985. We conduct a policy experiment which reproduces the 1988 constitution reforms that increased the retirement benefits and labor costs in the formal sector. We show that these reforms can explain the increase in informal labor. Then, we conduct a policy experiment and analyze its impact on the Brazilian economy.
